Question

The power dissipated in a resistor can be written as __________.

a. (ΔVR)²/ R
b IΔVR
c. I²R
d. All of the listed answers are correct.
e. None of the listed answers are correct.

Answer 1

The power dissipated in a resistor can be written as (d) All of the listed answers are correct. The formula for power dissipated in a resistor is P = I²R. For example, if the current through a resistor is 2A and the resistance is 5Ω, the power dissipated would be P = (2A)² * 5Ω = 20W.

Step-by-step explanation:

The power dissipated in a resistor can be written as d. All of the listed answers are correct.

The formula for power dissipated in a resistor is P = I²R. This means that the power is equal to the current squared times the resistance.

For example, if the current through a resistor is 2A and the resistance is 5Ω, the power dissipated would be P = (2A)² * 5Ω = 20W.
